My first thought on hearing this summary of Buddhism was how very much it reminded me of Rudolf Bultmann's definition of faith in keeping with the existentialist Christian tradition as depending on nothing but God, as letting go of all so-called certainties, including doctrinal and religious ones, which turn out to be idols when we cling to them.

Beyond the task of extricating women's liberation from the straightjacket of male-conceived leftist 'certainties' concerning emancipation, 'neofeminists', as the mass organisations sometimes referred to them, emphasised the distinct, equally systematic exploitation of women by men, adding women's sexuality and reproductive function as key sites of a power struggle, in addition to the relatively well-theorised impact of the capitalist mode of production on gender relations.

While the term postmodernism is often used to describe an aesthetic, artistic worldview characterized by a distrust of theories and ideology, I think it usefully applies (or rather should apply) to the "certainties" on both sides in the religion vs. atheism debate.
